CALENDAR.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed December 6, 1915. Serial No. 85,264.

To all whom it may concern I Be it known that I, JOHN L. MURRAY, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Calendar, of which the following is a full, clear, and exact descrip tion.

Among the principal objects which the present invention has in View are: to provide a calendar wherein intervals of time may be indicated for rapid successive adjustments; to provide means for varying the intervals; to provide means for indicating the initial and concluding dates of said intervals in accord with both the numerical monthly des gnation of the days and with the names-of the days of the week relative thereto; to provide a perpetual calendar rapidly and readily adjustable; and to provide a calendar such as described with means for mounting the same on a standing structure.

Drawings-"Figure 1 is a face view of a calendar constructed and arranged in accordance with the present invention; Fig. 2 is a sectional view of the same, the section being taken as on the line 2-2 in Fig. 1; Fig. 3 is a fragmentary View showing a porticn of the calendar and the position thereof when shifted from the position shown in Fig. 1.

Descriwtion.-As seen in the drawings, the names of the twelve calendar months are imprinted in their regular order on a circular disk 8. The names are imprinted as shown, between lines indicating sectors of the disk equal to one-twelfth of the circumference thereof. At the outer edge of the disk, calibrations 9 are placed indicating the three hundred and sixty-five days of the usual year. The disk 8 is superposed on a second disk 10, of slightly larger diameter, which has imprinted thereon fifty-two series of letters being the initial letters of the names of the days of the week, the letters being spaced in correspondence with the calibrations 9. The disks 8 and 10, a pointer 11. and hanger 12, are joined by and pivotally mounted upon a tubular rivet 13, all being independently rotatable thereon. The rivet 13 is contracted sufficiently to impose a frictional contact upon the said disks, pointer, and hanger, enough to require force to move any of the members from the adjusted positions. The hanger 12 has a Suspension eyelet 1st,

and is extended beyond the peripheries of the disks 8 and 10 to support the caliper arms 15 and 16 pivotally mounted on the hanger and on a tubular rivet 17. The arms 15 and 16 have each a target end 18, the center whereof is pierced to form a View opening 19. The opening 19 is sufficiently large to expose one of the letters indicating the day of the week and the mark indicating the day of the month. In service position, the arms 15 and 16 are spread, as shown best in Fig. 1 of the drawings, the target ends 18 on said arms overlying the edges of the disks 8 and 10.

The pointer 11 may be used in a variety of ways to indicate any future date, but it is preferably used in conjunction with the arms 15 and 16 to assist in shifting the disks 8 and 10 when moving the same to establish the next succeeding period. Thus in service the pointer 11 is placed as shown in Fig. 1 of the drawings, in a position marking the last day of the period indicated by the arms 15 and 16.

When it is desired to shift the calendar to indicate the next succeeding period for which the arms 15 and 16 are intended, the disks 8 and 10 are rotated on the rivet 13, the pointer 11 moving therewith. The disks are moved until the pointer indicates the center of the view opening 19 of the target end 18 on the arm 15, as shown best in Fig. 3 of the drawings. It will now be seen that the calendarhas been shifted and that the view openings 19 in the two arms 15 and 16 have remained permanently spaced so that where, as in the position shown in Fig. 1 of the drawings, the end of the period thereon indicated, is Sunday, August 30, in the newly established period the end thereof is indicated as September 27. The person using the calendar now shifts the pointer 11 to the new position, as shown by broken lines in Fig. 3 of the drawings, and the calendar is permitted to rest until the second period having expired, it is again shifted.

WVhile the calendar may be employed in the manner above indicated, it will also be seen that it may be used as a perpetual calendar. That is to say. the disk 10 may be shifted at the end of each year, so that the davs of the week on'the margin of the said disk will conform to the days of the month indicated by the calibrations 9 on the diskv 8. To facilitate the operation of spreading the arms 15 and 16, the hanger 12 is provided With a longitudinal slot 20, in which the rivet 17 may slide. This permits the placement of the target ends 18 in the most ing disposed in successive divisions corresponding With the numerically indicated divisions of the first-mentioned disk; a hanger for said disks; and a plurality of adjustable spanning members for indicating the mark ings on said disks, said spanning members being adjustable to increase or diminish the area covered thereby.

2. A calendar comprising a plurality of superposed disks of relatively different diameters for exposing the margin of the under disk, said disks being provided With marginal markings indicating on the one disk the annual divisions indicating month and day periods. the other of said disks having markings indicating-the days of the Copies of this patent may be' obtained for 1 ,2os,sse

Weeks and the successive Weeks into Which the annual period is divided; a pivot for salddisks; a hanger mounted on said pivot;

a plurality of spanner arms pivotall mounted on said hanger to overlie both of said disks for indicating dates thereon; and index members mounted on said arms.

3. A calendar comprising a plurality of superposed disks of relatively difl'erent diameters for exposing the margin of the under disk, said disks being provided with marginal markings indicating on the one disk the annual divisions indicating month and day aeriods, the other of said disks hav ing markings indicating the days of the Weeks; and the successive Weeks into which the annual period is divided; a pivot for said disks; a hanger mounted on said pivot; a plurality of spanner arms pivotally mounted onsaid hanger to overlie both of said disks for, indicating dates thereon; index members mounted on said arms; and a pointer mounted on said pivot for move-- ment with said disks, and independent of said disks for adjusting the same to succes siive unseparated divisions of time.
